Question 1

How do I use the Azure Anthropic API?

Accepted Answer

Create an LLM Gateway API key and point any OpenAI-compatible SDK at https://api.llmgateway.io/v1. Set the model to claude-sonnet-5-5. On pay-as-you-go keys, azure-anthropic/claude-sonnet-5-5 pins every request to Azure Anthropic; DevPass coding plans do not support provider pinning. You do not need a separate Azure Anthropic account or SDK.

Question 2

Which Azure Anthropic models are available?

Accepted Answer

LLM Gateway serves 9 Azure Anthropic models, including Claude Sonnet 5.5, Claude Opus 5.5, Claude Fable 5.1, Claude Opus 5, Claude Sonnet 5. Each model page lists per-token pricing, context window and capabilities.

Question 3

Does Azure Anthropic train on API data?

Accepted Answer

No. Azure Anthropic's published policy states that API traffic is not used for model training.

Question 4

Where is Azure Anthropic based?

Accepted Answer

Azure Anthropic is headquartered in United States. LLM Gateway shows each provider's location and data policy so you can route by compliance requirements.

Question 5

What happens if the Azure Anthropic API is down?

Accepted Answer

When you request a model without a provider prefix, LLM Gateway retries failed requests on other providers that serve the same model, so an outage at Azure Anthropic does not have to take your app down. Send X-No-Fallback: true with a provider-pinned model when every request must reach Azure Anthropic.
